  1. Sex differences were assessed via nonparametric Mann-Whitney U tests. ADOS scores represent calibrated severity scores (comparison scores). Two male participants are missing Vineland Adaptive Behavior Scales (VABS) scores. RRB = repetitive behaviors and restricted interests
  2. aCalibrated severity scores of 4 are equivalent to a raw score of 7 (ASD cut-off) and severity scores of 6 are equivalent to a raw score of at least 9 (autism cut-off) on the ADOS-2
